在全球变暖的背景下,高亚洲山地冰川受印度洋季风 和西风带的气候影响,大部分冰川出现了不同程度的消融 和退缩.同时,高亚洲作为除极地冰盖以外全球第二大的 冰川聚集地,是长江、怒江等亚洲7条河流的重要水源,被 称为“亚洲水塔”,养育世界1/3的人口,对区域内水资源、 水循环、气候与环境等有重要影响.然而,由于该区域地 形复杂、海拔较高等原因,只有少量的冰川具有实地观测 资料,难以开展大范围、高分辨率、...
川东地区发育典型的“侏罗山式”褶皱构造带,以北东走向的齐岳山断裂为界,南东侧为隔槽式褶皱,北西侧为隔挡式褶皱.中生代川东地区经历了自南东向北西的陆内递进变形,受多套滑脱层(基底拆离面、下寒武统页岩、志留系泥页岩和三叠系膏盐)的共同控制.但是,关于川东褶皱带的形成机制及其整体和分段形成时间仍存在较大争议.应用构造物理模拟方法,再现了川东“侏罗山式”褶皱带的形成过程,并分析了先存断裂及其倾角对川东褶皱...
